The servo motor drives the screw rod to rotate, so that all the dough making rollers 6 move in the same speed and direction along the length direction of the screw rod simultaneously. The linear movement and the rotation of the dough making rollers 6 are simultaneously carried out, so that each dough making roller 6 carries out the coating work of the fine sand rammed earth coating on the area between each two adjacent coating dividing lines.
The surface of the dough making roller 6 is divided into a uniform sand scraping surface 8, a gradual sand scraping surface 9, a pattern sand scraping surface 10 and a plane sand rubbing surface 11 in sequence in a circle. The central angles of the uniform sand scraping surface 8 and the gradual sand scraping surface 9 are both 120 degrees, and the central angles of the pattern sand scraping surface 10 and the plane sand rubbing surface 11 are 90 degrees. The surface making roller 6 is in contact with the surface of the wall body in sequence through the uniform sand scraping surface 8, the gradual sand scraping surface 9 and the pattern sand scraping surface 10 in the rotating process, and the smearing work of the fine sand ramming coating is completed. In addition, the plane sand-rubbing surface 11 can perform the rubbing work on the painted wall surface, and the rubbing work only aims at the painted part of the fine sand ramming coating higher than the uniform sand-scraping surface 8. The distance from the sand scraping surface 8 to the central shaft of the surface making roller 6 is equal, the distance from the sand scraping surface 9 to the central shaft of the surface making roller 6 gradually increases towards the direction of the pattern sand scraping surface 10, the distance from the pattern sand scraping surface 10 to the central shaft of the surface making roller 6 is equal to the maximum distance from the sand scraping surface 9 to the central shaft of the surface making roller 6, and the pattern sand scraping surface 10 is provided with strip-shaped protrusions 12 at intervals.
